Delmar Systems, Inc. continues to provide innovative solutions to the offshore oil and gas industry by using conventional anchor handling and rigging methods to perform platform toppling operations as part of the Gulf of Mexico’s Rigs-to-Reefs program. In June 2009, Delmar performed the toppling of BP’s decommissioned South Marsh Island 205B platform in a water depth of 523′ using the M/V Edison Chouest. Located approximately 90 miles off of the Louisiana coast, this toppled platform is the deepest offshore artificial reef of its kind.
For the South Marsh Island 205B platform, Delmar employed its conventional anchor handling and rigging methods and an anchor handling vessel (AHV) already working in the field to safely topple the platform. Successfully used for platform toppling operations in 2004, Delmar’s platform toppling methodology allows for optimal use of existing assets and greater efficiency; toppling operations for the 1700-ton portion of BP’s South Marsh Island 205B platform were completed in approximately 14 hours using a single AHV.
“As part of the decommissioning process, Delmar’s platform toppling services are a cost-effective alternative for the conversion of fixed jacketed structures into artificial reefs,” says Delmar’s Project Manager Josiah McVicar. “We can use an already contracted or spot-hired AHV to pull platforms over in a safe manner using existing equipment and techniques. This allows for schedule flexibility and significant cost savings to operators that want to convert decommissioned platforms into artificial reefs for the benefit of Gulf of Mexico marine life.”
